IIIIIPROVlEIVIEN'I' IN DIES FOR MAKING WATCH-CASE BEZELS.

Specification forming part of Letters Patent No. l @5,173, datedDecember 12, 1876; application tiled May 7, 1875.

To all whom it may concern:

Be it known that I, J osnrn FORTENBACH,

otCarlstadt, Bergen county, in the State of New Jersey, have inventedcertain new and useful Improvements in the Manufacture of Bezels forVatchCases, of which the following is a full, clear, and exactdescription, reterence being. `nad to the drawings, forming a part ofthis specification.

Watch-cases have heretofore been made in the following manner: The metalwas firs-t Bezels and centers were then drawn from the bars by adraw-bench through a draw plate or dies, then cut oft' in suitablelengths, soldered, and swaged down to a suitable shape and size. For thebacks and caps plates were rolled out through rollers to the requiredthickness, out in shape with shears, and swaged up by followers, madeusually of brass or composition. Snaps were then soldered on and thepieces finished up in lathes, and the required form given to them bymeans of gravers and different other and well-known tools.

l'the centers containing shoulders for bezels and caps, back and frontbacks, the bezels to their proper shape, and the covers containing snapsformed solidly thereto, thereby avoiding the necessity of solder andmuch manual labor in the attachment of such snaps.

To make bezels, which is the subject-matter of the present application,a round blank, Fig. l, is cut from a sheet of metal, and the shape givento it, as seen in Fig. 2, by means of dies, as shown in Fig. 3. Thepiece is then placed in dies shown in Fig. 4, and the shape given to itat the margin, as seen in Fig. 5, and by a second operation with thelast referred to lower die, and an upper die, such as shown in Fig. 6,not quite so deep as the former upper die, the outer rim is crowded downs0 as to increase the thickness ot' the bezel at the point where thesnap is formed, as seen in Fig. 7.

The piece is then put into dies shown in Fig. 8, and a round plate isout out ot' it, thus leaving the interior ot' the bezel suitable forworking on in the linishing of it up, as shown in Figs. 9 or 10.

I claim- 1. The combination of 'the dies shown in Figs. 3, 4, 6, and S,substantially as and for the purpose described.

2. The dies shown in Fig. 4, substantially `as described.
